These series are rebased on latest bleeding-edge, any comments are warm for me. See patch series of CPUPower in below git repo: V1: https://git.kernel.org/pub/scm/linux/kernel/git/rui/linux.git/log/?h=amd-pstate-dev-v1 V2: https://git.kernel.org/pub/scm/linux/kernel/git/rui/linux.git/log/?h=amd-pstate-dev-v2 V3: https://git.kernel.org/pub/scm/linux/kernel/git/rui/linux.git/log/?h=amd-pstate-dev-v3 V4: https://git.kernel.org/pub/scm/linux/kernel/git/rui/linux.git/log/?h=amd-pstate-dev-v4 V5: https://git.kernel.org/pub/scm/linux/kernel/git/rui/linux.git/log/?h=amd-pstate-dev-v5 V6: https://git.kernel.org/pub/scm/linux/kernel/git/rui/linux.git/log/?h=cpupower-amd-pstate Changes from V1 -> V2: - Refine the commit log for cpupower patches. - Expose a function to get the sysfs value from specific table. - Move AMD P-State sysfs definitions and functions into AMD helper file. - Move the boost init function into AMD helper file and explain the details in the commit log. - Remove the amd_pstate_get_data in the lib/cpufreq.c to keep the lib as common operations. - Move print_speed function into misc helper file. - Add amd_pstate_show_perf_and_freq() function in AMD helper for cpufreq-info print. Changes from V2 -> V3: - Revise the cpupower_amd_pstate_enabled() function to use cpufreq_get_driver helper instead of read sysfs. - Clean up the AMD P-State max/min frequency APIs, because they are actually the same with cpufreq info sysfs. Changes from V3 -> V4: - Introduce ACPI CPPC library support. - Clean up the duplicated AMD specific perf/frequency. Changes from V4 -> V5: - Fix the table check condition at cpufreq_get_sysfs_value_from_table. Changes from V5 -> V6: - Revise the minor commit and subject descriptions.
